PEMI2QFN/HG,115

Overview

The PEMI2QFN/HG,115 is a second-order low-pass EMI/RFI filter manufactured by Nexperia USA Inc. It utilizes an RC PI network topology to suppress electromagnetic interference in high-speed digital circuits. The component integrates two resistors with a resistance value of 45 ohms and a single capacitor with a capacitance value of 11 picofarads. Designed for surface-mount applications, it is housed in a compact 6-XFDFN package. This configuration provides effective attenuation of high-frequency noise while maintaining signal integrity for data lines.

Feature Summary

• Integrates a passive RC PI network structure for dual-channel filtering
• Provides second-order low-pass attenuation characteristics
• Designed for surface-mount installation in space-constrained layouts

Applications

• High-speed data line protection
• USB interface noise suppression
• General purpose EMI reduction in consumer electronics

Procurement Notes

Verify the specific suffix HG against official Nexperia documentation to confirm the exact pinout and internal component values. Ensure the selected variant matches the required 45-ohm resistance and 11-picofarad capacitance specifications for the target circuit design. Cross-reference the 6-XFDFN package dimensions with PCB footprint libraries prior to procurement.

Selection Notes

Select this component when a compact, dual-channel solution is required for attenuating common-mode or differential-mode noise on paired signal lines. The integrated nature of the RC PI network simplifies board layout compared to discrete components. Evaluate the 45-ohm series resistance impact on signal rise times to ensure compatibility with the operating frequency of the connected interface.

Part Context

This part belongs to Nexperia's family of EMI/RFI filters designed for protecting sensitive electronic interfaces. These components are engineered to meet stringent emission standards while occupying minimal board area. The use of a small form-factor package allows for integration into portable devices where space efficiency is critical for overall system miniaturization.
